Center Announcements

17th Workshop on Workflows in Support of Large-Scale Science @ SC22 Call for PapersThe Call for Papers for the 17th Workshop on Workflows in Support of Large-Scale Science is now open! The workshop focuses on the many facets of scientific workflow management systems, ranging from actual execution to service management and the coordination and optimization of data, service, and job dependencies. The workshop covers a broad range of issues in the scientific workflow lifecycle that include: scientific workflows representation and enactment; workflow scheduling techniques to optimize the execution on heterogeneous infrastructures; workflow enactment engines that deal with failures in the application and infrastructure; and a number of computer science problems related to scientific workflows such as semantic technologies, compiler methods, fault tolerance, etc. The paper submission deadline is August 15, 2022 AOE. For more information, see

Quantum Computing User Forum
The OLCF is pleased to announce that the 2022 Quantum Computing User Forum will be held on August 23. The purpose of the forum is to highlight the latest research from users of the Quantum Computing User Program and to build a community for exchanging ideas and resources within the field. The event will be strictly virtual due to local health and safety policies.  More information about the event, a list of confirmed speakers, and registration information are available here:

In addition, the user forum will host a one-day workshop on August 24th sponsored by IBM Quantum on scaling quantum computing applications. Registration for the user forum includes access to the virtual workshop and more details will be provided on the forum website.  If you have any questions, please contact

Meetings & Workshops

Using R on HPC Clusters Webinar
August 17,19 1:00 – 4:00 pm EDT

This OLCF hosted tutorial Webinar helps users learn a basic workflow for how to use R on an HPC cluster. The tutorial will focus on parallel computing as a means to speed up R scripts on a cluster computer. Many packages in R offer some form of parallel computing yet they rely on a much smaller set of underlying approaches: multithreading in compiled code, the unix fork, and MPI. The tutorial will take a narrow path to focus on packages that directly engage the underlying approaches, yet are easy to use at a high-level. This workshop is targeted for users of OLCF, CADES, ALCF and NERSC. Users who do not already have accounts on those system are welcome to attend the lectures but will not be able to participate in all of the hands-on activities.

AI for Science Bootcamp
August 25-26
NERSC, in collaboration with NVIDIA, will present a 2-day bootcamp designed to teach users fundamental concepts and practices in deep learning, and how to effectively apply them to scientific problems. Participants will learn how to implement the primary components of deep learning workflows, including hands-on exercises training, and evaluating custom deep-learning models on scientific datasets.

For more information and to register, please see Space is limited, and active NERSC/ALCF/OLCF users will be prioritized during the registration process.

Focus on Ally Skills WebinarAugust 30, 2:00 -3:00 pm  EDT

This webinar, brought to you by the ECP HPC Workforce Development and Retention Action Group, explains why allyship in the workplace is important and focuses on teaching specific ally skills such as listening, amplifying marginalized voices, and speaking up when it is uncomfortable. The invited speaker is  Valerie Aurora who is the founder of Frame Shift Consulting, the leading provider of ally skills training for technology companies around the world. She is a former software engineer and has taught practical, actionable ally skills to more than 4000 people in 11 countries. Registration is free and open the public.

Nsight Systems and Nsight Compute Profiling WorkshopAugust 31, 1:00 -3:00 pm EDT

NVIDIA® Nsight™ Systems is a system-wide performance analysis tool designed to visualize an application’s algorithms, help you identify the largest opportunities to optimize, and tune to scale efficiently across any quantity or size of CPUs and GPUs. This OLCF hosted workshop, given by NVIDIA, will show how to use Nsight Systems and Nsight Compute for tracing an HPC application. Users from ALCF, NERSC and OLCF are encouraged to register. If you do not have an account at one of those centers, you are welcome to register watch the lectures but we will not be able to provide you a compute resource for the hands-on parts of the course.

Please find more details and registration here:

Data Visualization & Analytics Series: ParaView at OLCF
September 15, 1:00 – 3:00 pm EDT

ParaView is an open-source data analysis and visualization application that allows users to quickly build visualizations to analyze their data. Available in both a GUI mode and a batch mode, ParaView is able to analyze extremely large datasets using distributed memory computing resources. This beginner friendly event will provide an overview of how to access ParaView at OLCF and a tutorial of how to use ParaView to visualize different datasets.

The hands-on component of this training is limited to users with moderate security enclave projects (i.e. able to access Summit/Andes), although others are welcome to sign up and attend the presentations. Additionally, hands-on examples will be available after the event for Moderate users to access and work with on their own. For more information or to register, see

OLCF GPU Hackathon 
October 17, 25-27
Do you have an application that needs to be ported to (or optimized on) GPUs? If so, why not work toward your GPU development goals surrounded by experts in the field? This hackathon is a multi-day coding event designed to help teams of three to six developers accelerate their own codes on GPUs using a programming model, or machine learning framework of their choice. Each team is assigned mentors for the duration of the event.

For more information, or to submit a proposal, please visit (The deadline to submit is August 17, 2022)

Upcoming Downtimes

– Andes, DTN, SPI DTN, and HPSS will be unavailable from 7:00 AM until midnight on Tuesday, August 23
– Work will be performed on Onyx and Marble from 8:00 AM August 23 until 8:00 AM August 24. During these times, Jupyter notebooks will be restarted, so in-flight processing will be halted but the notebook state will be stored. Otherwise, workflows should migrate between servers in the respective clusters and user impact is not anticipated.
